In the name of Allah The most gracious The most merciful
Astrophysics: Observations of distant galaxies and quasars show that these objects are redshifted which means that the universe is uniformly expanding everywhere.
An expanding Universe does not mean that everything in the Universe is growing in size. The galaxies are only moving away from each other! (Michael S. Turner & Craig Wiegert). The best words to explain this are mentioned in Quran (Enna lamosoon (create the vastness of the sky)).
(And the heaven We constructed with strength, and indeed, We are [its] expander.). (Quran 51:47)
